UNITED STATES V. SACIA. 761 �opinion as to the facts. It is for you to determine how far the testimony goes to satisfy you of the connection of the several defendants with the conspiracy. �I would suggest, however, that you take up the cases of each one of the defendants separately, and apply the testi- mony. For instance, consider the connection of Dr. Park. The testimony affecting him ia direct and circumstantial. The only direct testimony is that of Mrs. Lewis, and he as directly denies the connection as she unequivooally charges it.

I do not so interpret the duty of the jury. You may accept a portion of his testimony and reject another portion, if, comparing it with itself as a whole, and with the other witnesses, you are led to do 80.
